Rafe Kills Josef
Another moment we didn't see coming. Rafe chose the good of the many over the one (well, two, if you count he and Josef) by offing his pseudo-nephew. Specifically, he knew the Earth Republic would reign hellfire on Defiance is Josef wasn't "punished." The killing itself was a surprise - especially given how much Rafe values his loved ones - but also a turning point for Rafe. In the past, his obstinance would probably allow for the Earth Republic to come into town before he'd ever sacrifice a loved one. No longer the case.
